If one product is liquid and one is gel, as your post implies, this could explain the difference. Gel should only be used topically. The CS solution is more effective than gel since the silver is mobile. With a gel the silver is stationary and less is available (not mobile enough) to make contact with whatever needs to be killed. That being said, the CS is only effective when it is actually contacting the "bug," or whatever. Dan

The patent holders also sell the 10 ppm on the general market but I was told that the 10 ppm would be better for viruses and not to mention much cheaper. By the way, I own a Sota generator and just getting started making my own EIS but always wondered what the difference was between the two silver solutions. And yes, I've been taking this ready-made CS for many years and only found out about making it myself through this forum.
